ADHESIVE STRIP.

Application filed May 29, 1926.

This invention relates to a flexible strip of fabric or the like having marginal portions coated with adhesive material and an intermediate area free from the same.

l-leretofore flexible strips or tapes have been manufactured with one side thereof coated with adhesive material, and have been found useful for many purposes as for exampie for mending or binding articles, securing objects to each other, as well as for surgical dressings, and for various other uses. The present invention contemplates the provision of flexible strips of this character having semi-soft or plastic cement applied to its marginal portions with an intermediate portion free from cement, which may be provided with material suitable for surgical dressings, such as a light absorbent fabric, as for example gauze or the like. The strip of material may be conveniently provided for use rolls or otherwise as convenience of manufacture, shipping, storage or use may require. It may also be found desirable to provide temporary covering tapes for theadhesively coated margins, while in other cases these portions of the strip may remain uncovered.

While strips prepared in the manner disclosed herein are particularly useful in surgical dressings or the like, I am aware that there are various other arts in which strips of this character may also be advantageously used. The above and further objects and ad vantages and uses of the invention will be apparent to those skilled in the art upon a reading of the subjoined description and claims in conjunction with the accompanying draw ing in which:

Fig. 1 is a plan view of a strip partially unwound from a roll;

Fig. 2 is a section on line 2-2 of Fig. 1;

Fig. 3 is a similar view of another form of the invention; V

Fig. 4 is a view similar to Fi 1 of another form of the invention; and

Fig. 5 is a plan view of a modified form of the invention.

As disclosed in Figs. 1 and 2 of drawings a flexible strip 1, preferably formed of a somewhat porous or loosely woven fabric, has one face provided with adhesively coated margins 3 and 4. The adhesive material used for this purpose may be of various forms to suit various purposes and conditions of manufacture, but preferably comprises a semi-soft Serial No. 112,504.

or plastic cement of non-drying character, which is adapted to remain in adhesive condition indefinitely and is susceptible of use without requiring the application of heat or moisture to bring out its adhesive qualities. The adhcsively coated marginal areas 3 and 4 may be covered with light strips or tapes 5 and 6 of any suitable fabric which preferably will engage areas 3 and l in a less tenacious manner than the sheet or strip of fabric 1, so that they may be readily peeled from the strip 1 to leave the adhesive thereon.

The strip 1 is provided with an intermediate area 1 between the adhesive portions 3 and iwhich is free from adhesive. Light, porous fabric 7 such as gauze of the type commonly used for surgical dressing, may be applied to this part of the strip and secured thereto by portions which slightly overlap the adhesive areas 3 and 4 in order to hold the members 7 and 1 together. One manner, in which this concept may be carried out to provide an advantageous arrangement is shown in Fig. 1, wherein a plurality of layers of light absorbent and porous fabric 7 are folded back and forth over the area 1 with folded portions of the fabric in engagement with the inner edges of the adhesive areas 3 and 4;.

Another embodiment of the inventionis illustrated in Fig. 3, wherein a single thickness of gauze or the like is adhesively secured to the coated portions of the fabric and temporary covering strips 5 and 6 overlap the margins or the gauze.

Fig. l illustrates another advantageous form of the invention, wherein the interme diate layers of gauze or the like are omitted and the fabric is provided with marginal portions of cementitious material which may or may not be protected with temporary covering strips.

Fig. 5 shows another form of the invention wherein a short strip of fabric has a portion 13 about its perimeter coated with adhesive, and an intermediate portion 11 which is free from the same, and which may be provided with light porous material in themandisclosed in the preceding embodiments of the invention, if desired.

ltis evident that strips of the type disclosed herein are particularly useful in dressing a wound or sore when it is desirable to have the marginal portion of the dressing adhesively secured to the flesh of the patient and to have the intermediate portionleft free from adhesive and preferably somewhat porous as well as absorbent, in order to provide ventilation and a limited degree of absorption for the cut, wound, sore or the like. Formerly in dressing an injury or infected area it has been customary to provide a separate dressing of gauze or the like and to secure the same in place by separate strips of adhesive material; it being necessary not only to secure the adhesive tape to the flesh of the patient but to the marginal portions of the gauze or the like. Obviously the strip forming the subject-matter of the present invention maybe advantageously substituted for a dressing of this type, being more convenient to apply and better adapted to hold the gauze in place. Furthermore strips of the type, disclosed for example in Fig. 4t, may be used when it is not necessary to provide ahsorbent material over the wound or opcning in the flesh but is merely desirable to have the same protected by a strip of fabric with out having the adhesive come into contact with the wound or sore.

While the present invention presents outstanding advantages within the field of surgb cal or first aid dressings, it is to be understood that certain forms ot this invention are useful. in other arts, as for example the embodiment. illutrated in Fig. 41-, which may be applied to various locations, where it is desirable to secure a strip in place and yet not have the iDtOTll'lGCliflllG portion thereof coated with adhesive. For example, in the boot and shoe art the invention may be employed in form of a narrow stay or l'iinding' tape having plastic nonalrying cement along each margin or in the form of a sheet having; a stripe of adhesive at or near one margin and another stripe of adhesive spaced from the 1 irst stri pe, the tape or sheet being folded. and stitched be tween the two stripes.

I claim:

1. A surgical dressing comprising a strip of loosely woven fabric, one face of sa i-Ll strip having margins coated with adhesive material and an intermediate uncoated portion, and an absorbent and porous fabric upon the intermediate portion of the loosely woven fabric, said fabric slightly overlapping at least one adhesively coated portion of the loosely woven fabric, whereby it is secured to the latter, said uncoated portion of the loosely woven fabric and the porous fabric being adapted to provide ventilation through a con tinuous intermediate area of the dressin. it

2. A surgical dressing comprising a strip of loosely woven fabric, one face of said strip having marginal portions coated with adhesive material and an intermediate uncoat ed portion temporary covering meansrfor said coated portions and an absorbent and porous fabric covering the uncoated portion of the loosely woven fabric, said last-named fabric slightly overlapping at least one adhesively coated portion. of the fabric, VVllOlGr by it is secured to the latter, said uncoated portion of theloosely woven fabric and the porous faln'ic being adapted to provide ventilation throughout the continuous intermediate area oi. the dressing.

3. A surgical dressing comprising a strip 7 HAROLD A. EVANS.
